位势论

位势论中边界极限的研究

On the Study on Boundary Limits in Potential Theory

简介狄氏型理论。该理论已成为紧密联系解析位势论与马氏过程理论的强有力数学工具，并因此在数学与物理中有许多应用。

This survey paper is aimed to describe shortly the theory of Dirichlet forms , with the emphasis that this theory has become a powerful mathematical tool combining closely analytic potential theory and the theory of Markov processes , and hence has brought fruitful applications to mathematics and physics .

狄氏型源于数学物理中的经典位势论。

Dirichlet forms originated from the classical potential theory in mathematics and physics .

实质性规划理论包括本体论、城市森林生态位势论和城市森林规划的维度三部分内容。

Theories in urban forest planning include urban forest planning ontology , urban forest niche and ecological circumstances theory , and urban forest planning dimensions .

城市森林生态位势论研究城市森林发展的内在的动力机制问题，使规划符合城市森林发展的客观规律。

Urban forest niche and ecological circumstances theory studies inherent dynamical mechanism of urban forest development , and makes sure that planning conforms to objective rules of urban forest development .

本文以研究内在机制为目标，阐明城市复合生态位位势、城市界面论、城市奇异吸引源、城市增熵等4个方面的人为灾害灾变动力机制，并指出了这些研究结论的意义。

To study the inherent mechanism , this paper expounded the four dynamic mechanisms of man - made hazards , i. e. urban complex niche potential , limit theory , strange attractive source and added entropy , and pointed out the significance of these conclusions .
